Graphite powder has high conductivity. The conductivity of graphite powder is an important factor in the conductive finished product of graphite powder. There are many factors that affect the conductivity of conductive graphite powder, such as the ratio of graphite powder, external pressure, environmental humidity, humidity, and even light. The following methods can usually be used to measure the conductivity of graphite powder:

1. Voltammeter method for measuring resistance

Specific method: Use a precision small range electricity meter or a resistance multimeter to measure and compare the experiment. You can use a small light bulb to measure its conductivity based on its brightness. If the light bulb is brighter, it indicates a smaller resistance.

2. Measuring the conductivity of conductive graphite powder through resin method

Go buy some resin for conductive paint, add the same amount of conductive graphite powder, and then apply it on a board to measure its conductivity using a digital multimeter.

3. Some other factors for measuring the resistivity of conductive graphite powder

The conductivity varies with external factors and is relatively sensitive. Early microphones were all made of graphite powder, because the vibration of sound changed the conductivity between the graphite powder, resulting in the generation of analog signals by changing the current. It can be imagined that you need the experimental environment requirements for measuring his conductivity.
